The current biosphere assessment uses knowledge accumulated so far that it is desirable to introduce the latest knowledge to make a reliable assessment. At that time, it is also necessary to confirm the difference with the past parameter values. In this study, we conducted a follow-up survey of the sources of environmental transfer parameters used in biosphere assessment.
